  4. Diseases of Crop Plants:-

  • Major Fungal, bacterial, viral, viroids, phytoplasmal and nematode diseases of cereals, millets, oilseeds, pulses, fruits, vegetables, plantation, fiber, spices and ornamental crops with special reference to etiology, disease cycle/transmission and integrated management. Post harvest diseases in transit and storage and management. Phanerogamic parasites and Non-parasitic Diseases of crop plants and their management.

 5. Principles of Plant Pathology :-

  • Plant disease concepts, biotic and abiotic causes of plant diseases. Survival and dispersal of important plant pathogens, role of environment and host nutrition on disease development. Host parasitic interaction, infection process, disease development: role of enzymes, toxins, growth regulators. Defense mechanisms. Altered plant metabolism as affected by plant pathogens. Genetics of resistance ‘R’ genes, mechanism of genetic variation in pathogen, molecular basis for resistance and genetic engineering of disease resistance.

 6. Laboratory and Analytical Techniques:-

  • Preparation and sterilization of common media. Methods of isolation of pathogens and their identification. Preservation of
    microorganisms in pure culture. Methods of inoculation. Measurement of plant disease. Molecular detection of pathogens in seeds and other planting materials. Laboratory equipment and their use: autoclave, hot air oven, laminar flow, spectrophotometer, electrophoresis, light and electron microscopy, incubator, ultracentrifuge.

 7. Epidemiology and forecasting of plant disease :-

  • Concepts in epidemiology. Development of disease in plant population. Monocyclic and polycyclic pathogens. Role of environment and meteorological factors in the development of plant disease epidemics. Survey, surveillance (including through remote sensing), and prediction and forecasting of diseases. Epidemic analysis and prediction models. Crop loss assessment.

 8. Mushroom production Technology :-

  • Mushroom cultivation, food, medicinal value, uses of mushroom, edible and poisonous mushrooms. Life cycle of cultivated mushrooms, maintenance of pure culture, preparation of spawn and facilities required for establishing commercial spawn lab.
